This new report also provides an analysis of Apple sapphire related patents as well as recent sapphire substrates price trends and forecast and updated supply and demand analysis.

The sapphire industry recently ended a long period of depressed pricing and achieved US$936 million in revenue for wafer products in 2013. Recovery was helped by an increase in LED demand due to accelerating adoption in general lighting and a resilient LCD backlight market. But the saving grace was new consumer electronic (CE) applications: camera lens and fingerprint reader covers, mostly driven by Apple in 2013. Adoption at other vendors is progressing at a slower pace than anticipated in 2014. LG even reversed the trend with its

flagship cellphone: its G2 model featured a sapphire lens cover but the G3 uses glass. However, Yole’s analysts are optimistic for the mid-term with adoption increasing in Taiwan and China. In addition, new applications such as LED fi laments could further increase sapphire consumption.

After almost 2 years of losses, the price of sapphire cores increased more than 50% in 2013. In Q2-2014, tier-1 sapphire vendors were finally selling at breakeven prices. However, Yole expects that prices will decrease again in Q4.

In November 2013, GTAT and Apple announced partnership to set up a large sapphire manufacturing plant in Mesa, Arizona. Yole’s thorough analysis concluded that the objective of the investment is to produce sapphire display covers for cell phones.

“Apple plans to introduce both a 4.7” and a 5.5” model this year”, announces Dr Eric Virey, Senior Analyst at Yole. “We believe that prices for the sapphire cover have been agreed upon and locked by contract, based on yield assumptions reflecting reasonable expectations from all partners. We used yield assumptions derived from other Tier-1 sapphire makers in the LED industry to model the cost for both sizes. For the finished 4.7” display, we estimate a cost of $16, including $6.7 at the slab (material) level. On the longer term, we see a path for <$13”, he adds. Under those assumptions, Yole also estimates that the supply chain could deliver more than 5 million display covers per month.

But the challenges in term of ramp up execution are unprecedented in the industry. Recent checks point to bottlenecks at various levels of the process with lower than anticipated crystal growth and finishing yields. As of August 2nd 2014, Yole estimates that the supply chain capacity is currently ~2.1 million units per month. If yields don’t improve rapidly, Apple walking away from sapphire is still a possible scenario. The company believes that moderate quantities of supplemental material is currently being sourced from GTAT equipment customers in China. But even if all partners manage to improve yields rapidly, Yole’s analysis still excludes the possibility that sapphire can be used on all models of the new 2014 iPhone. However, Yole still expects that at least one model (SKU) will be offered in 2014 with a sapphire cover. This would allow Apple to plant a stick on the ground and make a statement. Scarcity could even be a good marketing tool providing it doesn’t last too long and that the supply chain catches up quickly. Releasing at least one SKU with sapphire would allow Apple to gage customer response and decide if it should adopt sapphire on more models, plan for more investment in the supply chain or simply walk away.

For the procurements of wafers for camera lens and fingerprint reader covers, Apple is now taking a back seat and letting their Chinese finishing contractors handle the sourcing. This resulted in accelerated commoditization (strong price pressure) and shifted large volumes toward Chinese sapphire vendors. Combined with current high levels of inventories, this has significantly impacted established vendors since the beginning of the year.

Procurement has started for the iWatch and is so far mostly benefiting Chinese vendors as well. Various designs have surfaced including one with a curved display (“2.5D design”) which would be more expensive to produce.”In any case, we expect that Apple will keep tapping into the existing supply chain and let GTAT focus on display covers”, says Eric Virey.

Yole’s report, August 2014 update, includes a thorough analysis of the GTAT/Apple deal. It explains key hypothesis of our cost model and provides thorough yield sensitivity analysis for cost and capacity. Cost, capacity and revenue models are presented for both 4.7” and 5.5” displays.

As IP and IC designers and verification teams tackle increased complexity and expectations, reliability verification has become a necessary ingredient for success. Automotive, always-on mobile devices, IOT and other platforms require increasingly lower power envelopes and reduced device leakage while maintaining overall device performance. Foundries have also created new process nodes targeted for these applications. Having the ability to establish baseline checks for design and reliability requirements is critical to first pass success. January 08, 2018Sponsored by Mentor Graphics

Since 2006, many of new 3D NAND Flash cells have been proposed and commercialized on the market. Already, we have seen 3D NAND cell structure up to 64L/72L with single or multi-stack NAND string architecture. The memory density on Micron/Intel’s 64L 3D NAND 256 Gb/die reached 4.40 Gb/mm2 (256 Gb/die). In this session, we’ll overview 3D NAND Flash roadmap, products, cell design, structure, materials and process integration. The 3D NAND cell architecture from major NAND manufacturers including Samsung TCAT V-NAND, Toshiba/Western Digital BiCS, SK Hynix P-BiCS and Micron/Intel FG CuA will be reviewed and compared. Current and future technology challenges on 3D NAND will be discussed as well.

MEMS have quite different process and material requirements compared to mainstream microprocessor and memory types of devices. We will explore the latest trends in MEMS devices – including sensor fusion, biosensors, energy harvesting – new manufacturing challenges and potential equipment and materials solutions to those challenges.
